What is WnetEnhance?

WnetEnhance (or Wajam) is yet another browser add-on that belongs to the ‘adware’ and ‘potentially unwanted program’ categories. The most important thing that you have to know about this program is the fact that it’s commonly distributed along with other freewares and sharewares. It may be attached to download managers, games, PDF creators, media players and similar programs as an ‘optional download’. Therefore, you should be very careful when installing free programs on your PC in order not to end up with WnetEnhance adware. Otherwise, your web browser may be flooded with commercial advertisements, you may continuously experience redirects to suspicious third-party websites, your PC’s system may slow down, your browsing habits may be investigated and so on. Yes, you have understood it correctly! WnetEnhance is a deceptive application that may initiate all aforementioned activities with an intention to earn the money for its developers. If you skip it unnoticed and install unconsciously, it may install a root certificate, which is named as WNetEnhance_root_cer into the Windows Trusted Root Certification Authority. This certificate is the main component of this app, which enables advertisements to appear during your browsing sessions. Besides, it may also allow this app to accumulate information about your browsing activities and habits. However, it may also see your login information. By the way, you should be aware that gathered information may be used for preparing WnetEnhance ads. That’s why they usually contain various deals and discounts related to the items that you have recently viewed or searched for. Unfortunately, we highly recommend you to stay away from ‘Ads by WnetEnhance’, ‘Powered by WnetEnhance’, ‘Ads by Wajam’ and similar notifications because they may be related to suspicious third parties and may trick you into visiting really suspicious websites without even suspecting that. To prevent WnetEnhance redirects, slowdowns, and privacy-related issues, we recommend you to run a full system scan with FortectIntego or another reliable anti-spyware and remove this adware ASAP.

How can WnetEnhance hijack my computer?

WnetEnhance is a misleading browser add-on that may infiltrate your computer behind your back. That’s probably what has recently happened to you and you feel slightly confused because you quite sure that you haven’t downloading this add-on manually. In fact, most probably this adware infiltrated your PC’s system via other freeware or shareware. Be aware that its developers rely on a ‘bundling’ distribution method most of the time because this method is legitimate but deceptive enough to make hundreds of people to install this adware without even noticing it. Fortunately, it’s not difficult to check freewares whether they contain ‘optional downloads’. For that, you just have to select Advanced or Custom installation option and carefully monitor the entire installation process. Read every notification carefully and try to find out a check box that contains a list of ‘optional downloads’. If you find any browser add-ons, plug-ins, toolbars or extensions promoted and set by default, make sure that you unmark ticks claiming that you agree to install them. Otherwise, WnetEnhance ads may start bothering you every time you browse the net.
